No you can't, not until youtube forbids videos with burned in ads and sponsored shit and paid mentions and all that garbage.

I pay for youtube premium and its totally worth it, but I do hate those vids that put advertisements into them. At least some put it at the end which I am ok with

I've seen a lot sponsored by Brilliant.something or so. Usually kurzgesagt, but on others too. I guess it must be a good ROI paying those high-profile channels for the ammount of subscriptions they must reel in.

Agree, and I'm read to pay for Chrome Premium ( or as it is called now - Brave browser )

That's not YouTube's job. Just as it's not a theater owner's job to forbid product placement in movies. Remember Pepsi in WWZ?

That's what the "unsubscribe" button is for.

(And what future video adblockers will be capable of.)

There is already an extension thac blocks sponsored parts. I think it was called sponsor block. Works very well

I wouldn't say 'very well', from what I've seen of it in the last couple weeks. The crowd sourcing is not particularly reliable. (Why do you think I'd want to skip 2 seconds in the middle of a conversation just because a sponsor got mentioned?)
